Let Rf = [A±1] be the algebra of Laurent polynomials in the variable A and let Ra = [A±1,z 1,z2,] be the algebra of Laurent polynomials in the variable A and standard polynomials in the variables z1,z2,. For n 1 we denote by VBn the virtual braid group on n strands. We define two towers of algebras {VTLn(Rf)} n=1 and {ATLn(Ra)} n=1 in terms of diagrams. For each n 1 we determine presentations for both, VTLn(Rf) and ATLn(Ra). We determine sequences of homomorphisms {ρnf:Rf[VB n] VTLn(Rf)} n=1 and {ρna:Ra[VB n] ATLn(Ra)} n=1, we determine Markov traces {Tnf:VTL n(Rf) Rf} n=1 and {Tna:ATL n(Ra) Ra} n=1, and we show that the invariants for virtual links obtained from these Markov traces are the f-polynomial for the first trace and the arrow polynomial for the second trace. We show that, for each n 1, the standard Temperley–Lieb algebra TLn embeds into both, VTLn(Rf) and ATLn(Ra), and that the restrictions to {TLn}n=1 of the two Markov traces coincide.

虚拟和箭头 Temperley–Lieb 代数、马尔可夫迹和虚拟链接不变量

RF = [一种±1]是变量中的 Laurent 多项式的代数一种然后让R一种 = [一种±1,z 1,z2,]是变量中的 Laurent 多项式的代数一种和变量中的标准多项式z1,z2,.为了n 1我们表示VBn虚拟编织组n股。我们定义了两个代数塔{VTLn(RF)} n=1{ATLn(R一种)} n=1在图表方面。对于每个n 1我们确定两者的演示文稿,VTLn(RF)ATLn(R一种). 我们确定同态序列{ρnFRF[VB n] VTLn(RF)} n=1{ρn一种R一种[VB n] ATLn(R一种)} n=1,我们确定马尔可夫迹{n'FVTL n(RF) RF} n=1{n'一种ATL n(R一种) R一种} n=1,我们证明了从这些马尔可夫迹中获得的虚拟链接的不变量是F-多项式用于第一道,箭头多项式用于第二道。我们证明,对于每个n 1,标准 Temperley-Lieb 代数TLn嵌入两者,VTLn(RF)ATLn(R一种),并且限制{TLn}n=1两条马尔可夫轨迹重合。
